BELL PEPPER Plants~what's the BEST way to plant them--in pairs??

Question:and what type of nutrients do they like??
thank u!

Answers:
Plant them in blocks,so that when they are full grown, they will be just touching .(~ 15-16" apart) This allows for better pollination , shades out much of the weeds that would ordinarily grow, and keeps the roost cooler and moister .
